Hypomania is not as intense as mania. For example, you may be pacing, full of energy, talking fast, and racing thoughts, but at the same time you are not a complete ball of energy. Like you may just be much more energetic but not necessarily clean the whole house at 2:00 a.m. You just don't go up as high. I have hypomania and not mania.
Psychosis can happen sort of any time, from what I understand, either in deperssion or mania. I would ask these questions of your doctor, too.
